Summary
Real-time three-dimensional dynamic navigation system (3D-DNS) is a feasible tool for post space preparation (PSP). This system improved accuracy and efficiency compared to freehand methods, enhancing safety in root canal treatments.
Area of Science:
- Endodontics
- Dental Technology
Background:
- Post space preparation (PSP) is critical for root canal-treated teeth.
- Ensuring accuracy and safety during PSP is essential to prevent complications.
Purpose of the Study:
- To evaluate the feasibility of a real-time three-dimensional dynamic navigation system (3D-DNS) for PSP.
- To compare the accuracy and efficiency of 3D-DNS with the freehand (FH) method for PSP.
Main Methods:
- Fifty-four maxillary molars were divided into 3D-DNS and FH groups.
- Cone beam computed tomography (CBCT) was used for pre- and post-operative scans.
- 3D deviations, angular deflections, residual dentin thickness (RDT), operation time, and mishaps were recorded.
Main Results:
- 3D-DNS demonstrated significantly higher accuracy with fewer deviations and angular deflections than FH (P < .05).
- The 3D-DNS group required less operating time (P < .05).
- No 3D-DNS samples had RDT < 1 mm, compared to 6/27 in the FH group.
Conclusions:
- 3D-DNS is a feasible technology for post space preparation in vitro.
- The 3D-DNS system enhances the accuracy and efficiency of PSP.
- Dynamic navigation shows potential as a safe and reliable technology for PSP.
